    <thetext>~39 pre-existing JSC test failures are noticed on JSCONLY EWS on trunk, both on MIPSEL and JSCv7.

e.g.:
MIPSEL: https://ews-build.webkit.org/#/builders/25/builds/168/steps/17/logs/stdio

JSCv7: https://ews-build.webkit.org/#/builders/26/builds/147/steps/17/logs/stdio

    <thetext>These failures do not seems to happen on build.webkit.org bots. So it might be a configuration issue.

e.g.:
https://build.webkit.org/builders/JSCOnly%20Linux%20MIPS32el%20Release/builds/4016
https://build.webkit.org/builders/JSCOnly%20Linux%20ARMv7%20Thumb2%20Release/builds/9942</thetext>

    <thetext>I can reproduce 3 of them locally both on arm and mips, 2 of which have just appeared on the arm buildbot: https://build.webkit.org/builders/JSCOnly%20Linux%20ARMv7%20Thumb2%20Release/builds/10119/steps/jscore-test/logs/stdio

I made a patch to (properly) skip them that&apos;s about to land:
https://bugs.webkit.org/show_bug.cgi?id=204522

(2 are timeouts and one is supposed to be skipped but the runDefault was added before the skip in a recent change).</thetext>

    <thetext>This has now been fixed and both ARMv7 and MIPSel are green with JIT enabled since r257466 (bug 208196).

Closing this.</thetext>
